"The Postal Service will showcase some of the more compelling historic, full-disk images of the planets obtained during the last half-century of space exploration. Some show the planets' ""true color"" like Earth and Mars — what one might see if traveling through space. Others, such as Venus, use colors to represent and visualize certain features of a planet based in imaging data. Still others (red storms on Uranus) use the near-infrared spectrum to show things that cannot be seen by the human eye. Credits: USPS/Antonio Alcalá © 2016 USPS"
